Quality of Earnings 101: What a QoE Report Actually Tells You (and What It Costs)

Every seller's profit and loss statement tells a story about how profitable the business is. A quality of earnings (QoE) report is what happens when someone independent checks that story against the underlying source data, transaction by transaction, instead of taking the summary at face value. It's the single highest-leverage piece of diligence you can commission, and most first-time buyers have only a vague idea of what it actually involves.

What a QoE report is (and isn't)

A QoE report isn't an audit. An audit gives an opinion on whether financial statements comply with accounting standards, is expensive, and is rarely used in small business or online business deals. A QoE report instead rebuilds the business's real, recurring, cash-backed earnings from the ground up, using bank statements, payment processor data, and platform records rather than the seller's own summary, and flags anything that doesn't hold up.

For an online business specifically, that means reconciling revenue against Stripe or PayPal statements, ad platform spend against actual invoiced amounts, and traffic claims against Google Analytics or Search Console data, rather than just checking that a spreadsheet's math adds up internally.

What it actually checks

• Revenue verification. Does claimed revenue match what actually landed in the business's payment processor and bank accounts, month by month, not just in an annual total that's easy to round favorably?
• Addback scrutiny. Sellers routinely add back personal expenses, one-time costs, and owner perks to arrive at seller's discretionary earnings (SDE). A QoE report tests whether each addback is legitimate and reasonably sized, since inflated addbacks are one of the most common ways an asking price ends up higher than the business's real earnings support.
• Revenue and traffic concentration. How much of the revenue or traffic depends on one channel, one customer, one affiliate program, or one search ranking. This directly feeds into the multiple a buyer should reasonably pay, since concentrated earnings are worth less per dollar than diversified ones.
• Trend and seasonality. Whether earnings are genuinely stable or growing, or whether recent months are propped up by something temporary, like a one-time promotion or a spike that already reversed by the time you're looking at the deal.
• Off-book liabilities and red flags. Unpaid refunds, chargebacks trending upward, aged payables, or anything else that doesn't show up cleanly in a basic profit and loss statement but affects what the business is actually worth.

What it costs and how long it takes

Cost scales with how deep the review goes. A basic financial review, enough to sanity-check a smaller deal, commonly runs $2,000 to $5,000 and takes one to two weeks. A full QoE engagement, more appropriate for a larger or more complex acquisition, commonly runs $30,000 or more and can take up to eight weeks. Between those two ends, providers offer scaled options sized to deal size, which is worth asking about directly rather than assuming you're stuck choosing between a light review and a full engagement.

When it's worth it, and when it's not

For very small deals, a light, low-cost review is often enough, sometimes combined with doing more of the reconciliation work yourself against the seller's raw payment processor exports. As deal size grows, so does the case for a fuller engagement: the dollar amount at risk from an inflated addback or a concentration problem you miss grows right along with the purchase price.

Most experienced buyers commission this work after signing a letter of intent, once exclusivity gives them the time and the seller's cooperation to actually gather the source data, rather than before an offer is even on the table.

Next: once you know what a QoE report can tell you, negotiating price and terms is where those findings actually get put to use.
